Specification of Letters Patent. Application filed March 29, 1911.

Patented July 4, 1911. serial No. 617,570.

To all whom it may concern: Y

Be it'known that I, CYRUS DoLPH, a subject of the King of Great Britain, residing at Preston, in the county of Waterloo, Province of Ontario, Canada, have invented a new and useful Metallic Shingle, of which the following is a specication.

The invention relates to improvements in metallic shingles.

The object 'of the present invention is to improve the construction of metallic shingles, and to provide a simple, inexpensive and elicient shingle, adapted to be readily laid on the sheathing or other roof boards, and capable of being overlapped and interlocked so as to effectually prevent rain from beating in under the shingles, or in any other manner getting to the roof boards.

A further object of the invention is t0 piovide a metallic shingle of this character, adapted to permit an expansion and contraction of the parts incident to changes in temperature without loosening the fastening devices, and equipped with means for draining any water, which may accumulate in the joints or locks.

With lthese and other objects in view, th invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended; it being understood that various changes in thel form, proportion, size and minor' details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings r-Figure 1 is a perspective view of two shingles, constructed in accordance with this invention and interlocked at their contiguous side portions. Fig. 2 is a similar view, showing three shingles, and illustrating the manner of overlapping and interlocking the shingles at the top and bottom. Fig. 3 is a transverse sectional view, taken through the side locks of a plurality of shingles. Fig. 4 is a longitudinal sectional view, taken through the top and bottom locks of a plurality of shingles and illustrating the manner of securing the same to the roof boards. Fig. 5 is a detail perspective view of the lower portions of tw'o shingles, illustrating the construction `of the side and bottom locks, and showing the parts before the bottom locks are brought into alinement. Fig. 6 is a similar view, the bottom locks being in alinement. Fig. 7 is a detail perspective view of the upper portion of the shingle, the top lock .belng bent upward or opened at one end'to show the extension of the right hand side lock.- Fig. 8 is a lan view of the blank from which the roo ng plate is constructed. l

Like characters of reference designate-corresponding parts in all the ligures of the drawings.

In the accompanying drawings in which is illustrated the preferred embodiment of the invention, l designates a metallic shingle, constructed of sheet metal and adapted to be manufactured either plain or in ornamental patterns of any preferred design. T he shingle is made from the substantially rectangular piece of sheet metal of the form illustrated in Fig. 8, and it is provided with top, bottom and side locks, being interlocked at each of its marginal edges with the adjacent shingles. The top lock is formed by bending the shingle plate upwardand backward near its upper edge on the dotted line A in Fig. 8, forming an approximately U- shaped portion 2, and it is then bent upward and backward over the said U-shaped portion 2 on the dotted line B of Fig. 8, and is extended beyondV the U-shaped portion to provide a nailing strip 3, which is bent on the dotted line C of Fig. 8 to enable the nailing strip to fit Hat against the roof boards 4, as clearly illustrated in F ig. 4 of the drawings. The bending of the sheet metal back on the U.shaped portion 2 forms an upper ply or thickness la an interlocking flange of two thicknesses. Also the bending 0r folding of the metal in this manner provides for the necessary contraction and expansion incident to changes in temperature and prevents the same from loosening the nails 5, or other fastening devices for securing the nailing strips to the roof boards.

The lower edge of the shingle plate is bent under and folded back on the line D of Fig. 8 to form an approximately U- shaped bottom lock or portion 6,which hooks into and interlocks with the U-shaped portion of the top lock, whereby the shingles are overlapped and interlocked at their up` per and lower edges. The bottom lock 6 extends to the right hand side of the shingle, as clearly indicated in Fig. 8, and the lower ange or portion. is recessed or cutaway at 7 at the left-hand end to permit the bottom locks of two adjacent metallic shingles to fit practically together in flush relation, a sufficient space occurring between the adjacent ends of the bottom locks to allow water collecting within the side locks to drain therefrom and run ofll onto the next lower shingle. f

The shingle plate is folded upward and backward on the dotted line E of Fig. 8 to form a substantially U-sha ed Portion and to provide the right hand slde lock 8. The upper flange or portion of the right hand side lock is provided at the top with a tapered extension 9 of approximately triangular shape, extending beyond the first fold of the top lock to the second fold thereof, thereby overlapping the inner face of the. U-shaped portion 2 of t-he top lock and arranged within the same. This effectually closes both the upper end of the side lock of the shingle and the right hand end of the U-shaped bend 2 of the top lock, so that a driving storm will not force water up out of thel upper end of the side lock, nor can it force water along the underside of the upper portion of the vU-shaped bend 2 and out at the right hand end of the top lock. The side lock is formed prior to the bending or folding of the sheet metal at the top of the shingle plate, and the folding of the latter to lform the top lock presses the extension 9 into close contact with the inner face of the U-shaped portion 2 of the top lock. The lower portion of the right hand side lock is provided in its upper face with a longitudinal groove or gutter 10, extending from the top to the bottomlock and adapted to permit water blown into the side locks to collect within it and to drain olf through the space between the adjacent ends of the bottom lock onto the next lower shingle. This will prevent the water accumula-ting in the sidelocks from creeping or being forced around the folded portions of the sheet metal and entering the space beneath the shingles. Also" thegroove will carry off any water resulting, from the melting of ice, which may form aroundthe side locks.

The left'hand side edge of the shingle is bent or folded. downward and backward under the shingle to form the left hand side lock l1, which vis approximately U-shaped to provide a lower fiange to hook into and interlock with the upper flange of the right hand side lock. In assembling the metallic shingles, the side locks are hooked into each other, as illustrated in Fig. 1 of the drawings with the adjacent ends of the nailing strips in overlapped relation so that a single nail pierces and secures the overlapped terminals of the nailing strips. The bottom locks of the upper shingles are hooked into lthe U-shaped portions of the top locks, as

illustrated in Fig. 2 of thc` drawings, the upper row of shingles breaking joints with the next adjacent lower row. The top, bottom and'side locks are open sufficiently to enable the shingles to be easily and rapidly -interlocked with each other, and they do not require. any hammering or closing of the locks after they have been laid on a roof. When the shingles are interlocked, they form a perfectly water tight roof and are adapted to shed water, and through the draining means prevent water from collecting in the side locks.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A metallic shingle consisting of a plate of sheet metal and including a top lockr formed by bendingl the sheet metal upward and backward near its upper edge in o a substantially U-shaped portion and then bending' the sheet metal upward and backward over the said U-shaped portion, the metal being extended beyond the U-shaped portion to form a nailing strip, a right hand side lock formed by bending the side edge of the metal upward and backward to provide a U- shaped portion, the upper fiange of the side lock being provided at the top with a tapered extension extending beyond the first fold of the top lock and arranged within the folds of the said top lock to close the right hand end thereof and also the top of the side lock of the shingle, anda left hand side lock formed by folding the metal downward and backward to interlock with the right hand side lock.

2. A metallic shingle consisting ofa plate of sheet metal and including a top lock stantially U-shaped portion and then bending the sheet metal upward and backward over the said U-shaped portion, the metal being extended beyond the U-shaped portion to form a nailing strip, a bottom lock formed by bending the lower edge of the shingle downward and backward, and side locks formed by bending the side edges of the shingle in opposite directions to form interlocking U- shaped portions, one of the side locks being provided in the bottom of its U-shaped portion with a longitudinal groove or gutterextending from the top to the bottom locks for draining the water from the side locks.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.

CYRUS DOLPH.
